Python 3.7.0

[Luci2015]

The .pex package for Windows fails to run the script with the newest Python 3.7.0 version.
The error is the one with missing dependencies.
I see all the Win builds are constructed using Python 3.6.3.

When the pex file is created, the major python version is stamped at the top. This means it will only run if it matches the environment version. This is a pex thing, and I have not found a way to override it. You'd need to build it on 3.7 to run it there.

We're not targeting Python 3.7 for Windows at this time. Because the python-ldap library is difficult to build on Windows (and no wheel files are on PyPI for python-ldap win64), we rely on an unofficial build. The python-ldap version we use only has builds for Python 2.7, 3.4, 3.5 and 3.6.

We can get a build that targets 3.7, but it's a newer version of the library than the one we use (3.1.0 vs 2.4.45). It might be worth the effort to test 3.1.0 so we can do a 3.7 build, but not until a future release.

OK, the report is just to mention it, in case someone else searches for this until the enhancement is released.

Depends on #436

Closing this as we're planning on transitioning to drop pex in the future in favor of standalone executables that won't depend on an external Python interpreter.
